PT5303

PT5303 1.25W Mono Full Differential Audio Power Amplifier with Shutdown Select GENERAL DESCRIPTION The PT5303 is a fully differential audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.25W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V power supply. The PT5303 is designed specifically to provide high quality output power with a minimal amount of external components. The PT5303 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phones and other low voltage applications where minimal power consumption is a primary requirement. The PT5303 contains advanced pop & click circuitry which virtually eliminates noises which would otherwise occur during turn-on and turn-off transitions.
